DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a printed pattern or mark printed at regular intervals on a ceramic green sheet formed on a long carrier film wound in a roll shape. The present invention relates to a ceramic green sheet supply device for supplying to a stage.

[0002]

2. Description of the Related Art In a conventional ceramic green sheet supply apparatus, when a printing pattern or a mark on a ceramic green sheet formed on a carrier film wound into a roll is supplied to a processing stage, the following processing is performed. There were drawbacks.

[0003] Since it is wound in a roll shape, uneven winding generated at the time of winding is accumulated. As a result, when a printing pattern on a ceramic green sheet is supplied to a processing stage, it is positioned in the width direction of the ceramic green sheet. Misalignment occurs.

In order to correct the displacement in the width direction, conventionally, as shown in FIGS. 19 (a) and 19 (b), a supply roll section movable in the width direction of the ceramic green sheet by an actuator 30 is conventionally used. The ceramic green sheet 2 on the carrier film 1 sent out from 10 is
After passing through the roller 11, the carrier film 1 is peeled off from the carrier film 1 by the peeling roller 31 and supplied to the mesh conveyor 32. A processing stage 19 is provided on the transport path of the mesh conveyor 32.
, The internal electrode pattern 3 which is a print pattern of the ceramic green sheet 2 supplied to the ceramic green sheet supply position recognizing unit 33, the positioning mark 4,
Alternatively, the position of the position confirmation mark 5 is recognized, and the supply trajectory of the ceramic green sheet 2 is corrected. That is, the supply roll unit 10 itself is moved by the actuator 30 to correct the displacement of the ceramic green sheet in the width direction.

[0005]

In the prior art, since the supply trajectory in the width direction of the ceramic green sheet was corrected for the ceramic green sheet peeled from the carrier film, the transfer of the ceramic green sheet to the peeling roller 31 or the mesh conveyor 32 was performed. Sometimes they wrinkled or torn.

Further, since the ceramic green sheet in that state is recognized by the ceramic green sheet supply position recognition unit 33, there is a case where the position cannot be accurately recognized.

Even if the ceramic green sheet supply position recognition unit 33 recognizes the position of the ceramic green sheet and corrects the supply trajectory of the ceramic green sheet, the path between the recognition unit and the trajectory correction unit is long. The followability was poor, and it was difficult to reliably supply the ceramic green sheets to the processing stage 19.

Accordingly, the present invention provides a method for correcting the ceramic green sheet formed in a long carrier film wound in a roll shape in the width direction, that is, for correcting the supply trajectory of the ceramic green sheet and confirming the position of the ceramic green sheet. It is an object of the present invention to provide a ceramic green sheet supply device which enables detection to be performed with good followability and accurately supplies a ceramic green sheet to a processing stage.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a ceramic green sheet supply device according to the present invention will be described.

According to the present invention, the ceramic green sheet recognizes a positional shift in the width direction of the ceramic green sheet caused by uneven rolls, that is, detects a position confirmation mark formed at the same time as the print pattern in front of the processing stage. A configuration in which the carrier film is fixed on the carrier film by vacuum suction with a suction plate, a configuration in which the supply trajectory in the width direction of the ceramic green sheet is corrected together with the carrier film and the roll in the carrier film suction fixed state, After fixing the supply path in the sheet width direction, the ceramic green sheet is vacuum-adsorbed and fixed by the suction plate of the pick-and-press unit, then the carrier film is taken up via a separation blade, and the ceramic green sheet is separated and processed. Supply to stage Configuration is a ceramic green sheet supply device was.

In the state where the ceramic green sheet before the processing stage is on the carrier film, the position recognition in the width direction of the ceramic green sheet and the correction of the supply trajectory are performed. . Further, since the ceramic green sheet for which the supply trajectory has been corrected is peeled off from the carrier film, wrinkles and tears generated when the supply trajectory is corrected are eliminated. In addition, the present invention is very effective for ceramic green sheets having a small thickness because the transfer and position correction of the ceramic green sheets are performed on the carrier film.

From this state, the carrier film 1 is fixed by the suction plate 12 by vacuum suction. Thereafter, as shown in FIG. 8, the position confirmation mark detection sensor 17 (FIG. 7)
) Is advanced by the air cylinder 18.

The position of the moving end of the position confirmation mark detection sensor 17 is arranged so as to have the same relative position as the ceramic green sheet supply position required in the processing stage 19.

As shown in FIG. 9, the suction plate 12 that has fixed the carrier film 1 by vacuum suction is replaced with a motor 2.
0 (see FIG. 3) to move in the longitudinal direction,
Start transfer of the carrier film.

Therefore, as shown in FIG. 10, either the upper or lower position confirmation mark detection sensor 17 moves to the position where the position confirmation mark 5 is detected.

As shown in FIGS. 11 (a) to 11 (c), the motor 21 (see FIG. 5) is driven depending on the detection state, and the ceramic green sheet is passed through the rolled ball screw 22 (see FIG. 5). The position is corrected in the directions of the arrows B1 and B2, that is, in the width direction.

At this time, since the position of the ceramic green sheet on the carrier film is corrected for the entire unit including the carrier film and the supply and take-up rolls,
No wrinkling or breakage occurs in the ceramic green sheet during repair.

As shown in FIG. 12, when the position correction in the width direction is completed, the supply roll unit 10 (see FIG. 3) disposed in the supply roll unit 10 (see FIG. 4) is operated. , And the position confirmation mark detection sensor 17 is retracted by the air cylinder 18, and the pick and press unit 24 (see FIG. 4) completes the position correction in the width direction by the air cylinder 25 (see FIG. 3). It moves on the ceramic green sheet 2 which was done.

As shown in FIG. 13, when the movement is completed, the ceramic green sheet suction pad 26 (see FIG. 4) in the pick and press section 24 (see FIG. 4) is lowered, and the ceramic green sheet 2 is vacuum-adsorbed. And fix it.

After that, the vacuum suction of the suction plate 12 which has fixed the carrier film by vacuum suction is released, the suction plate is moved backward by the motor 20, and the ceramic green sheet 2 is separated from the carrier film 1.

As shown in FIG. 14, the carrier film 1 from which the ceramic green sheet 2 has been peeled off at this time is
It is wound on a winding roll by the tension of a motor 16 (see FIG. 3).

After the retraction of the suction plate is completed, the ceramic green sheet 2 is cut by moving the ceramic green sheet cutter 27 up and down, and the peeling of the ceramic green sheet 2 is completed.

As shown in FIGS. 15 to 18, after the ceramic green sheet suction pad 26 is raised, the pick-and-press unit 24 (see FIG. 4) is moved to the processing stage 19 by the air cylinder 25 and peeled off to the processing stage. The ceramic green sheet 2 is supplied.

Hereinafter, the ceramic green sheets are supplied to the processing stage 19 by sequentially repeating this operation.
